Hi yall, I’m trying to hunt down an idea and I’m hoping to find some leads. I’m wanting to build an RF Spectrum Analyzer using rather a raspberry pi or an esp32. I’m wanting it to look for frequencies in the 500-900 mhz range. I want it to function like an external search and select like you would find in mid to high end wireless microphone technology. I’m looking for simple leads like a similar project someone has done or maybe components that can detect these signals.

Any leads would be greatly appreciated!

Here is an expensive tool I’m essentially looking to simplify: https://www.sweetwater.com/store/detail/RFExplorerPro--rf-venue-rf-explorer-pro-spectrum-analyzer?mrkgadid=&mrkgcl=28&mrkgen=&mrkgbflag=&mrkgcat=&acctid=21700000001645388&dskeywordid=92700080454169695&lid=92700080454169695&ds_s_kwgid=58700008743176688&ds_s_inventory_feed_id=97700000007215323&dsproductgroupid=2318218814285&product_id=RFExplorerPro&prodctry=US&prodlang=en&channel=online&storeid=&device=m&network=g&matchtype=&adpos=largenumber&locationid=9026902&creative=705256640089&targetid=pla-2318218814285&campaignid=21453452330&awsearchcpc=1&gclsrc=aw.ds&gad_source=1&gclid=CjwKCAjw--K_BhB5EiwAuwYoyol-cmtqqiwBu3ZZjvfUY7Go0xKwLXXb1A2ZnzW74lxnQog7uT7fKxoCrqEQAvD_BwE

Hi good folks, does anyone have experience with transferable skills to other roles or industries? I am running out of options, and I don't know where to look.

I am a senior Antenna engineer, and I have been looking for the past few months without any luck. I get to final stages, but every company I talked to has a hiring freeze.

I do not understand why swinging the voltage at the gate of the input transistor (VG) from 0 to 1 at 60G leads to a minimal ripple in the drain current. I know that this large inductor L0, is forcing a DC current, but I am expecting that when the VG swings below the threshold voltage, the current should be fully directed to the output. At the output node , there is a 4Ohm resistor connected. Note the large DC current (82mA) which I generate by approximately 500 fingers of 1u wide. Looking for help understanding what is going on.

Searching for courses of RF Test and Measurement you can do online that is at least at an undergraduate engineering perspective from a university or some other resource that has proper course notes and so on and covers spectrum analyzers, power meters, network analyzers, signal sources/generators

any text/book suggestions would also be helpful or website, course notes etc

Hi all,

I am currently looking for new opportunities and have an offer for a signal integrity position for high speed digital differential signaling. It involves EM simulations in HFSS, measurements with VNA/TDR, and design of the connectors. The signals are used at up to 60 GHz.

My long term goal is to have a career in anything involving EM simulations such as antennas, waveguides, planar structures etc.

Now I am not sure if this position aligns well with my long term goals. Is SI engineering a good stepping stone for an EM simulation career or should I keep looking for other jobs in this domain? How easy/difficult would the transition to antenna design be later on?

Thank you for your help.

Hey guys, I'm currently starting a university project on filtering antennas (design and simulation on cst or ads). Does anyone know any helpful resources or books that specifically talk about the designing process? Thanks in advance!

Every open source design these days use ngspice as the default simulator. But the real question is about its accuracy. For designs over 100 GHz, how accurately can NgSPICE calculate S & Z parameters? The IHP Open PDK has a ft/fmax of 350/450 GHz. How accurate would a 100 GHz design with the SG13G2 technology be which is simulated using NgSPICE?

I'm trying to make some calculations for a PA (I'm thinking about doing my thesis about this) but unfortunately I can't download a tutorial workspace that is stored here:

https://edadocs.software.keysight.com/display/eesofkcads/Tutorial%3A+Power+Amplifier+Design+in+ADS

It seems that I need to have a license but my university doesn't have one. It's basically the workspace used in those tutorials:

https://abhargava.wordpress.com/2021/05/15/ads-10-watt-gan-power-amplifier-workspace-is-now-available-for-download/

Can someone with the license download them and upload them to dropbox or google drive so I can get them?

I can invite you for a drink trough paypal as a compensation :)
